Embodiment
For above-mentioned feature, the advantage that makes the embodiment of the invention becomes apparent more, be elaborated below in conjunction with embodiment.
At first introduce the handshake mechanism of ima protocol.
According to the requirement of ima protocol, link establishment must be finished the state exchange of two cover state machines, the normal running status that two states that overlap state machines are all reached, and only in this way, communication equipment ability operate as normal promptly can the transceiver network data.Wherein, this two covers state machine is respectively link state machine and group state machine.Link state machine comprises the receiving link status machine and sends link state machine.
With the proximal device is example, and its receiving link status machine state exchange comprises following step:
1, proximal device will be in the pairing link configuration of receiving link status machine of Not In Group state in IMA virtual link group;
At this moment, the state of receiving link status machine is the Unusable state by Not In Group state exchange.
2, proximal device receives ima protocol control (ICP, the IMA Control Protocol) cell from remote equipment;
3, receive icp cell after, proximal device is checked the parameter of icp cell;
The icp cell parameter of proximal device inspection comprises: the effective identification information of logical number (Logical ID) in receiving terminal mistake, link obstructions report, the IMA group.
4, if each parameter all is positioned at correct scope, the state of receiving link status machine is the Usable state by the Unusable state exchange;
5, proximal device continues to receive icp cell, and when the transmission link state machine of the icp cell report remote equipment that receives had been converted to Usable state or Active state, the state of receiving link status machine was the Active state by the Usable state exchange.
The group state machine of this proximal device carries out state exchange can comprise following step:
1, after proximal device was set up IMA virtual link group and link added into corresponding IMA virtual link group, the state of group state machine was the Start-up state by Not Configured state exchange;
2, proximal device receives the icp cell from remote equipment;
3, when the group state machine of the icp cell report remote equipment that receives was in Start-up state or Start-up-Ack state, the state of group state machine was the Insufficient-Links state by the Start-up state exchange;
4, according to the parameter configuration of IMA virtual link group, the state of group state machine is the Operational state by the Insufficient-Links state exchange.
For example: it is the Active state that the receiving link status machine of at least one link is arranged in the parameter configuration requirement group of IMA virtual link group, so, when the receiving link status machine of a link of IMA virtual link group reached the Active state, the state of group state machine was the Operational state by the Insufficient-Links state exchange.
To sum up, proximal device is if think normal receiving network data, need when path setting, receive the icp cell that the match state conversion requires, finally make the receiving link status machine of this proximal device be in the Active state, make group state machine be in the Operational state according to ima protocol.Remote equipment only just can send the icp cell that comprises handshaking information to proximal device when path setting.When operate as normal, as long as proximal device no longer sends the signaling that is used to shake hands to remote equipment, remote equipment will keep normal condition, and no longer comprises handshaking information in the icp cell that near-end sends.
